BitTorrent client written in C++ and based on libtorrent-rasterbar. qBittorrent-nox is a version of qBittorrent (Qt5 application) that does not require X and can be controlled via a WebUI, thus is more suitable for headless servers. It is a feature rich but lightweight client that is very similar to rTorrent. Its main features are:

* Remote control through a Web user interface * Vuze-compatible protocol encryption * uTorrent-compatible Peer eXchange (PeX) * DHT (trackerless) support * UPnP / NAT-PMP port forwarding * IPv6 compliant * Advanced control over torrent content and trackers * IP Filtering (eMule / Peer Guardian filters) * Torrents queueing and prioritizing * Good localization (~25 languages supported) * Unicode support
